Hello,

As changing the Virtual Domain Name didn't solved the issue in the following thread, I got a question. Is it possible to change the Virtual Domain Name instead of changing the Hostname, to make it different ? Will that be difficult ? I read somewhere that the value of the Virtual Domain Name is stored somewhere in the database.

Thanks.
